Question

How do you simplify `(t^0s^-2) / k`?

Answer 1

`1/(ks^2)`

Explanation:

Simplifying requires some of the laws of indices.

`color(magenta)(x^0 = 1) " "0^0 " is undefined"`

`color(blue)(x^-m = 1/(x^m)) " makes negative indices positive"`

Apply these two laws.

`(color(magenta)(t^0)color(blue)((s^-2))) / k = color(magenta)(1)/(kcolor(blue)(s^2)`?

=`1/(ks^2)`
